Why do high-precision plane and prism optical parts need to be rechecked before processing?

1. In the process of machining, various reasons (such as equipment error, improper operation, etc.) will affect the accuracy of parts. Re-inspection can find and correct these problems in time and ensure the accuracy of processing.

2. If the parts are not rechecked, once nonconforming products appear, the quality of the whole batch of parts will be affected. Re-inspection can find and eliminate unqualified products in time and avoid unqualified products in mass production.

3. In the process of machining, parts will be deformed for various reasons (such as temperature change, stress release, etc.). Re-inspection can find and correct these problems in time and ensure the stability of parts.

4. In the process of machining, the size of parts will change, thus affecting the interchangeability of parts. Re-inspection can find and correct these problems in time and ensure the interchangeability of parts.
